Feature Film Scripts - Optioned

If a feature film script is optioned but never produced, can it still be considered "for educational purposes" as the qualifying exemption from copyright infringement if used by scriptwriters to study in writing their scripts?

Does the production of the script have anything to do with infringement besides establishing the length of protection afford the script writer?

Thanks,
